Channel LEDS and status bits
The table below shows the LEDs behavior, the description and the corresponding status bits.

(Status bit)
State & Description
C0 to C7
(Pin 2 & 4)
OFF
No error
DI configured but not activated
DO configured but not energized
Fixed green
No error
DI activated.
DO energized.
Fixed red
CSx=1
DO: when shorted to ground
OVUB =1
DO energized and UB overvoltage
OLUB =1
DO energized and UB overload
UVUB =1
DO energized and UB under voltage
OVUL =1
DO energized and UL overvoltage
UVUL =1
DO energized and UL under voltage
OLUL=1
DO energized and UL overload
PSx=1
L+ is shorted (Pin 1)
CSx: Channel Status (x = Channel number)
UVx: Under Voltage (x = UL or UB)
OVx: Over Voltage (x = UL or UB)
OLx: Over Load (x = UL or UB)
PSx: Port Status (x = Channel number) - state of the pin1 (L+)
Note
If L+ is shorted (Pin 1) or Pin4/Pin2 are shorted, the 2 LEDs port will be fixed red but the
digital outputs will continue to be driven by the PLC.
Note
There is no short detection on Pin 3 and Pin 5. They are all protected against short.
Communication breakdown strategy
In the event of loss of bus communication (released or lost) or when ETHERNET/IP scanner goes to Idle mode
(PROG mode), the following strategy will be applied:
- the configurable digital outputs fallback values (reset or hold) will be applied.
- the digital inputs keep reporting to the ETHERNET/IP scanner (no impact)
